Nceda qaphela! Ezi zine zifriji ziyatsha kwaye ziyadubula!

1. Ifriji eyi-R32

I-R32, ekwabizwa ngokuba yi-difluoromethane kunye ne-carbon difluoride, ayinambala kwaye ayinaphunga, kwaye inezinga lokhuseleko le-A2. I-R32 ithatha indawo yeFreon eneempawu ezintle zethemodynamic. Inempawu zenqanaba lokubila eliphantsi, uxinzelelo lomphunga kunye noxinzelelo, umlinganiso omkhulu wefriji, ixabiso lelahleko le-ozone, umlinganiso omncinci wokusebenza kwendlu eluhlaza, onokutsha kunye nesiqhushumbisi. Umda wokutsha emoyeni yi-15% ~ 31%, kwaye uya kutsha uqhume kwimeko yedangatye elivulekileyo.

I-R32 ine-viscosity coefficient kunye ne-conductivity ephezulu yokuqhuba. Nangona i-R32 inezibonelelo ezininzi, i-R32 sisiqandisi esinokutsha nesiqhumayo. Ukufakwa kunye nokugcinwa kwomoya opholileyo kuyingozi eyindalo. Ngoku kudityaniswa nezinto ezingaqinisekanga ezingama-R32, imiba yezokhuseleko kufuneka ithathelwe ingqalelo. Ukufakelwa kunye nokudityaniswa kwezixhobo zefriji ze-R32 kufuneka kukhutshwe.

2. Ifriji eyi-R290

I-R290 (propane) luhlobo olutsha lwesikhenkcisi esinobungqongileyo, esisetyenziswa ikakhulu kwizipolisi zomoya, impompo yokufudumeza impompo yobushushu, izixhobo zokupholisa umoya ekhaya kunye nezinye izixhobo zefriji ezincinci. Njengefriji yehydrocarbon, i-R290 inexabiso le-ODP elingu-0 kunye ne-GWP elingaphantsi kwama-20. Xa kuthelekiswa nezikhenkcezisi eziqhelekileyo, i-R290 inezinto ezibonakalayo eziluncedo kokusingqongileyo, njengoko kubonisiwe ngezantsi:

2.1 Ukutshatyalaliswa kocwecwe lwe-ozone nge-R22 efrijini yi-0.055, kwaye umlinganiso wobushushu behlabathi ngu-1700;

2.2 Ukutshatyalaliswa kocwecwe lwe-ozone nge-R404a ifriji yi-0, kwaye umlinganiso wobushushu behlabathi ngu-4540;

Ukutshatyalaliswa kocwecwe lwe-ozone nge-R2.3A ifriji yi-410, kwaye umlinganiso wobushushu behlabathi ngama-0;

2.4 Ukutshatyalaliswa kocwecwe lwe-ozone nge-R134a ifriji yi-0, kwaye umlinganiso wobushushu behlabathi ngu-1600;

2.5 Ukutshatyalaliswa kocwecwe lwe-ozone nge-R290 yefriji ngu-0, kwaye umlinganiso wobushushu behlabathi ngu-3,

Ukongeza, ifriji eyi-R290 ineempawu zokufudumeza okungaphezulu kokungabikho komphunga, ukufudumala okuhle, kunye nokonga umbane. Nangona kunjalo, ngenxa yeempawu zayo ezinokutsha kunye neziqhushumbisi, inani lokufakwa ngaphakathi lilinganiselwe, kwaye inqanaba lokhuseleko li-A3. Umshini uyafuneka xa usebenzisa i-R290 yebanga lefriji kwaye amadangatye avulekileyo avumelekile, kuba umoya (ioksijini) ukuxubana kunokwenza imixube eqhumayo, kwaye kukho ingozi yokutsha kunye nokudubula xa udibana nemithombo yobushushu kunye namalangatye avulekileyo.

3. R600a ifriji

I-R600a isobutane luhlobo olutsha lwefriji yehydrocarbon enentsebenzo egqwesileyo, ethathwe kwizithako zendalo, ayonakalisi umaleko weozone, ayinampembelelo yendlu eluhlaza, kwaye inobuhlobo kwindalo. Iimpawu zayo bubushushu obukhulu obufihlakeleyo bokungumphunga kunye namandla okupholisa awomeleleyo; ukusebenza kakuhle kokuhamba, uxinzelelo lokuhambisa olusezantsi, ukusetyenziswa kwamandla okuphantsi, kunye nokunyuka kancinci kweqondo lobushushu bomthwalo. Ihambisana kunye izinto zokuthambisa isiguquli. Yiyigesi engenambala kwiqondo lobushushu eliqhelekileyo kunye nolwelo olungenambala kunye nolubonakalayo phantsi koxinzelelo lwalo. I-R600a ubukhulu becala isetyenziselwa ukufaka endaweni yefriji eyi-R12, kwaye ngoku isetyenziswa kakhulu kwizixhobo zefriji yasekhaya.

Umthamo wokuqhushumba we-R600a ifriji yi-1.9% ukuya kwi-8.4%, kwaye inqanaba lokhuseleko yi-A3. Inokwenza umxube wokuqhuma xa uxutywe nomoya. Ingatshisa kwaye iqhume xa ifunyenwe kwimithombo yobushushu kunye namalangatye avulekileyo. Isabela ngendlela enobundlobongela ngee-oxidants. Umphunga wayo unzima kunomoya. Inxalenye esezantsi isasazeka ukuya kumgama omkhulu, kwaye iya kulayita xa udibana nomthombo womlilo.

4. R717 (ammonia) ifriji

4.1 Okokugqibela, masithethe ngefriji eyi-R717 (ammonia). I-Ammonia iyingozi ngaphezu kwezi ntlobo zintathu zingasentla zeefriji. Yeyesidanga esinetyhefu kwaye inqanaba letyhefu.

4.2 Xa uxinzelelo lwevolumetric yomphunga we-ammonia emoyeni ufikelela kwi-0.5 ukuya kwi-0.6%, abantu banokuba netyhefu ngokuhlala kuyo kangangesiqingatha seyure. Uhlobo lwe-ammonia lumisela ukuba ukusebenza kunye nokugcinwa kwenkqubo ye-ammonia kufuneka kulawulwe, kwaye abasebenzi abakhenkcezisi kufuneka banikele ingqalelo kuyo xa beyisebenzisa.
